You spent (likely) years learning Emacs. How much time did you spend learning each of those IDEs you've tried?
You have to realize that psychologically: you like things you're familiar with, and dislike things you're unfamiliar with. That's how top-40 radio works. That's why everybody bitches over every new software update, even when the new version is provably better.
So of course you like the thing you spent years with over the thing you tried to learn for a week and a half then gave up on because Emacs is better. That has nothing to do with UX.
